Tompoodie,
You're right, I was reading your thread title and didn't pay attention to the fact that all the units mentioned in your text are phono stages; my comments were regarding line stages. The Atma-Sphere preamps actually use 12AT7s in the phono section and 6SN7s for output buffering. There are some DIY octal phono stages:

which probably sound great, but no commercial 6SN7 phono stages that I know of. It's tough to get enough gain out of 6SN7s for phono duty.
